The ruble or rouble is the currency of the Russian Federation and the two self-proclaimed republics of Abkhazia and South Ossetia. Formerly, the ruble was also the currency of the Soviet Union and the Russian Empire prior to their breakups. Currently there is no official symbol for the ruble.

The Saudi riyal has been the currency of Saudi Arabia since the country came in to being and was the currency of Hejaz before Saudi Arabia was created. In June 1986, the riyal was officially pegged to the US Dollar at a fixed exchange rate of 1 U.S. dollar = 3.75 riyals.
